TIRE-"BOLvT-WRENCH MACHINE.

SPECIFICATION formingpart of Letters Patent No. 790,587, dated May 23,1905.

Application led June 14, 1902. Serial No. 111,661.

To all whom t may concern:

Be it known that I, CLEMENT L. V. MUND- HENK, a-citizen of the UnitedStates, residing at Marion, in the county of Grant and State of Indiana,have invented certain new and useful Improvements vin Tire-Bolt-WrenchMachines; and Ido declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertainsto make and use the same, reference being hadto the accompanying In the annexed drawings, illustrating this4invention, A is a metal frame cast in one piece having a backvertical supporting-plate m, with side projections m at the top and bottom, with lplate.

slotted openings for the purpose of securing the frame rigidly to asuitable object for use, a pair of 'jaws for the pivoting-leverextending outward from the face of theback plate 'm at the top, joinedto said back plate m below said jaws, a top plate m extending outward,having near its center suitable openings f to receive and supportavertical bevel-gear wrenchshaft C, said plate m being joined at itsouter extremity to a face-plate m3, which projects at right anglesdownward. Upon the upper end of said front frame-plate is a fixed jaw d,adjustable by means of a set-screw, said front plate having atconvenient points means of attaching and supporting the bevel-gear shaftand lever B. Extending outward from the lower end of said back plate mto the lower end of said front plate m3 is a bottom plate mi, formingaunion at right angles With said front Extending outward from the 'backplate at a point alittle below the top plate m is a plate m2, parallelwith said top plate, but

extending only part way, said plate having near its extremity a suitableshaft-opening c, l corresponding to and with the one, f, de-

having at its upper end a jaw d, provided with' a cutting-blade it,inserted in an opening upon its front face corresponding to the fixedjaw el and cutting-blade, as described as a part of the frontframe-plate m3, said lever being provided at its lower extremity with ayoke V, as shown in Fig. 3, constructed to engage an eccentric locatedupon a shaft, hereinafter described, operating in conjunction with saidlever, said lever having at a convenient point a suitable opening forpivoting and operating in conjunction with eccentric-shaft to bedescribed, producing a cutting device for removing the projecting end ofa bolt. D is a short metal cast link-lever having a pivoted end upon oneend engaging the jaws upon the face-plate heretofore described, saidlink-lever having at a point on its under side and directly over thecenter of wrench-socket, Fig. et, hereinafter described, a dog j', atits other end a round bearing-pin engaging a lever E, operating inconjunction therewith.

In Fig. l, E is a metal cast lever having a slightly-curved handle endand downward and inward curved hook Z to engage the felly of a j wheelto form a fulcrum, said lever having at a convenient point a slottedopening extending through said lever in a plane with the round end of,the short link-lever last described suitable to engage the roundbearing .end of said short link-lever and permitting the adjustment ofsaid curved lever-hook to different points on a felly when the machineis in use.V

Fig. 4: is a hollow shaft having at one end a wrench-socket to be usedas a wrench, having IOO an opening on one side through which thedisengaged nut may be discharged, the said shaft adapted to engage withand be operated by a train of bevel-gears working in a vertical planefastened to a shaft and supported by the shaft passing through theframe-plates at convenient points below the top plate. Said shaft has asa part of its construction an eccentric conveniently located to engage ayoke V, Fig. 3, on a lever heretofore described, and acrank at rightangles to a line of its location in the frame, Figs. l and 2. Abevel-gear engages the above-describedv gear, working in a horizontalplane at a point between the top plate and the one described as belowit, Fig. 2.

I am aware that tire-bolt machines have been made with vertical andhorizontal bevel-gear and shafts operating in conjunction with anutwrench. I therefore do not claim such a combination broadly; but

What I do claim as my invention, and desire to secure by Letters Patent,is

In a tire-bolt-wrench machine the combination of a vertical metal castframe A, having vertical and horizontal plates, a cutting-jaw upon thefront face-plate, suitable openings in plates to receive and support abevel-gear and shaft, a short metal link-lever pivoted to the jaws inthe back frame-plate, said lever having a dog and round hearing end toengage with metal cast hand-lever E through a longitudinal slotted hole,said lever having a handle end and a curved hook end to engage with thefelly of a wheel in use, a sq uare socketwrench with side opening andshaft, a lever having a pivotal center with a cutting-jaw upon its upperend to engage with a corresponding fixed cutting-jaw and a yoke upon itslower end to engage with a shaft having an eccentric thereon, said shaftprovided with a bevel gear-wheel engaging with a wrenchsocket-shaftgear-wheel, said shaft operated by means of a crank and handle,substantially as speciiied.

In testimony whereof I have signed my name to this specilication in thepresence oi two subscribing witnesses.

CLEMENT L. V. MUNDl-IENK.
